A UW–Madison researcher was part of a global collaboration has just released a satellite-based map of world croplands that “found” 625 million to 875 million acres that were not known to national agricultural authorities.

Rockd serves both amateur rock lovers and professional geologists, says Shanan Peters. "People see rocks at highway cuts, and some may wonder what they are and when they formed. The answers ... exist in the databases that we tap into."

Staff at the Arthur H. Robinson Map Library at the University of Wisconsin–Madison used their resources to help track down the site where a 130-ton B-52 bomber crashed in the dark on Nov. 18, 1966, near unincorporated Hauer in Sawyer County in northwestern Wisconsin.
